Abstract
A power tool includes a housing, a motor that is disposed within the housing and defining a first axis, and a tool holder driven to oscillate about a second axis by the motor. The second axis is perpendicular to the first axis. The power tool also includes a vibration dampening assembly with a counterweight that is configured to reciprocate along a third axis that is perpendicular to both the first axis and the second axis in response to oscillation of the tool holder about the second axis.
Claims19
A power tool comprising:
- a housing;
- a motor disposed within the housing and defining a first axis;
- a tool holder driven to oscillate about a second axis by the motor, the second axis being perpendicular to the first axis;
- a drive mechanism configured to convert continuous torque from the motor to continuous oscillating movement of a tool accessory received by the tool holder;
- and
- a vibration dampening assembly disposed in an interior of the housing, the vibration dampening assembly including a counterweight configured to reciprocate linearly along a third axis perpendicular to both the first axis and the second axis in response to oscillation of the tool holder about the second axis, the third axis being positioned above the first axis defined by the motor.

- and
- a vibration dampening assembly disposed in an interior of the housing, the vibration dampening assembly including,
- a case supported by the housing,
- a counterweight positioned within the case, the counterweight configured to reciprocate linearly along a third axis perpendicular to both the first axis and the second axis in response to oscillation of the tool holder about the second axis, the third axis being positioned above the first axis defined by the motor,
- a first spring arranged between the case and the counterweight, the first spring biasing the counterweight in a first direction, and
- a second spring arranged between the case and the counterweight, the second spring biasing the counterweight in a second direction opposite the first direction;
- wherein the first and second springs are coaxial with the third axis and bias the counterweight toward a neutral position within the case.
